Abstract (en)
[origin: WO2019243493A1] Compact radiofrequency exciter comprising at least one axial access intended to be connected to a radiating antenna, at least one output intended to retrieve received signals and at least one input intended to transmit signals, characterised in that the exciter comprises a first and a second septum polariser and a frequency filter, the second polariser being connected, via its common access, to a first rectangular access of the first polariser, and the frequency filter being connected to the second rectangular access of the first polariser and being configured to filter a reception or transmission frequency band, these two bands being different, and characterised in that at least one of the polarisers is configured to convert a circularly polarised signal received on said axial access of the exciter into a linearly polarised signal for a reception frequency band and in that at least one second polariser is configured to convert a linearly polarised signal transmitted to said exciter by said input into a circularly polarised signal for a transmission frequency band.
